WHEELED GUN-CARRIAGE.

Specification of Letters Patent.

Patented Feb. 10, 1920.

Original application filed May 26, 191*), Serial in. 171,267. Dividedand; this application filed October 22',

To all whom it may concern:

Be it known that I, EMILE BIMAILHQ, a citizen of France, residing inParis, France, have invented a new and Improved Wheeled Gun-Carriage, ofwhich the following is a full, clear, and exact description.

My invention relates to wheeled gun carriages, and has reference moreparticularly to the trail construction of the carriage, forming adivisional matter of my application, Serial No. 171,207 filed May 26,1917.

The object of the present invention is the construction of a guncarriage in which the front part of the trail system is provided withextensions.

On the drawings annexed Figure 1 is a plan of the gun carriage, thetrails being open and extended for firing, a portion of the structurebeing broken out to show the details of construction; and

Figs. 2 and 3 are similar views of car riages showing a modifiedconstruction of the trails.

As the gun carriage which we are considering must, with a view to roadservice, exhibit the usual arrangement of a carriage with single centraltrail, these trails have been designed according to the arrangementshown on the drawings. The male part 1 of a ball and socket joint isfixedly connected to the trail frame 22. This trail frame is in theshape of a V or a horse shoe, the branches 23 of which have sockets fortrail beams, marked 6 and 7, in which said beams are free to slide. Thetrail beams have a pivotal connection with the branches 23 through themedium of a link 34. The link has a pivotal connection with a branch 23and with a beam. The links, beams, and branches 23 have openings adaptedto register when the trail beams form a continuation of the branches 23,these openings being engageable by bolts 40. See position shown in fulllines in Fig. 1. The trail beams in that position have a contact withthe lateral wall 24: in the enlarged end of the socket of the branches23.

The road position of the trail is mdicated in dotted lines in Fig. 1. Tobring the trail beams into said position, the bolts 40 must be removed,when the trail beams 6 and 7 can be swung on their pivots 2, which ispermitted by the enlarged sockets 3 of the extensions 23. The trailbeams can then be Serial 259,205.

pushed toward the axle to bring the openings in the end thereof for thebolts 40 in register with the openings of extensions 38 of the axle andsecured thereto by pins 36. When the trail beams are so connected, thebutts of the trails will come in contact on the longitudinal axis of thecarriage and may be bolted by any suitable device.

In the modified form shown in Fig. 2, the ends of the trail beams at thelinks 3 1 swing inwardly. The passage for the ends of the trail beams isformed in the upper part of the branches 23 to bring the ends of saidtrail beams into engagement with the extensions 37 and the axle to whichthey may be secured. In this construction the enlarged sockets 0 of theextensions are eliminated,

and the construction permits a greater shortening of the trail in thefolded or road position.

In the modification shown in Fig. 3, the branches 23 have a brace 4 towhich the ends of the trail beams 6 and 7 may be connected. For thispurpose, openings are provided in the brace 4 with which the endopenings of the trail beams may register when they fold against oneanother, as shown in full line in Fig. 3, the dotted lines indicatingthe firing position. The contact of the trail beams 6 and 7 allow forroad transit a greater angle for the degree of turn which the limber maymake.

I claim:

1. A wheeled gun carriage comprising an axle frame, a. trail frame, apivoted connection between the axle frame and the trail frame, trailbeams having slidable engagement with the trail frame, links connectingthe trail frame and beams, means for lock ing the links to the trailframe and beams to hold the trail beams diverging, and means for lockingthe trail beams to the axle frame to hold them converging.

2. A wheeled gun carriage comprising an axle frame, a trail framepivotally mounted on the axle frame, trail beams, links pivotallyconnecting the beams to the trail frame so that said beams may formextensions of the trail frame or be connected to the axle frame, andmeans for lockingsaid beams to either the trail frame or the axle frame.

3. A wheeled gun carriage comprising an axle wheel frame, a V-shapedtrail frame pivotally connected to the axle frame, trail of the beams tothe axle frame when said beams are swung on the links to converge.

4:. A wheeled guncarriage comprising an I axle frame, a trail framepivotally mounted on the axle frame, trail beams, links pivotallyconnecting the trail beams and the trail frame so that said beams maydiverge or converge, and means for locking said beams in diverging orconverging position.
